Note:
1. Measured from high line to low line.
2. Measured from full load to zero load.
3. Output ripple and noise measured with 10uF tantalum and 1uF ceramic capacitor across output.
4. Logic compatibility: Open collector ref to -Input. Module ON >3.5VꢀC to 75VꢀC or open
circuit. Module OFF <1.2VꢀC.
Load share accuracy
10% at 50% to 100% full load.
Auxiliary voltage/current 10 3VꢀC/20mA max.
5. Suffix “N” to the model number with negative logic remote ON/OFF.
Module ON <1.2VꢀC. Module OFF >3.5VꢀC to 75VꢀC or open cicruit.
6. Trim-up: Connect a resistor between +Vout and +sense. Trim-down: Connect a resistor
between the trim pin and -sense
7. The input external capacitor recommend to parallel with 220 uF/450V ESR<0.7W to reduce
the input ripple voltage.
